Abstract The densification process of sintered alumina is mainly controlled by surface, lattice, and interface diffusion,
and many experimental researches show that heating rate can affect the transfer of matter. Thus, to further
reveal the effect of heating rate on sintering mechanism of alumina nanoparticle, molecular dynamic
simulations were performed at five different heating rates to examine the migration of atoms and evolution
of microstructure in heating stage. Results show that the sintering process of heating is a typical thermal
activation process. High displacement response temperature is caused by high heating rate, which results in
the mechanism of atomic migration quickly… More >
